Biohazard and Crime Scene Remediation in Oak Grove, OR

Oak Grove is an unincorporated community and census-designated place in Clackamas County, Oregon, with a population of 17,290 at the 2020 census and 7,276 households in the 2020 census.

Oak Grove was named at the suggestion of Edward W. Cornell, a member of the surveying party that platted the townsite in the 1890s, after the crew ate lunch in a stand of oak trees in the northwestern part of the tract.

The area was first served from the Milwaukie post office, and in 1904 the Creighton post office was established, named for Susan Creighton, on whose donation land claim the office stood, with noted Oregon botanist Thomas J. Howell as its first postmaster.

Postal authorities would not name the office Oak Grove at first because an Oak Grove post office already existed in Josephine County, but in 1907 the Post Office Department changed the post office name to Oak Grove and renamed the Center railroad station to match, though the railroad no longer passes through the community.

Oak Grove is located in northwestern Clackamas County, bordered to the north by the city of Milwaukie, to the east by unincorporated Oatfield, to the south by unincorporated Jennings Lodge, and to the west by the Willamette River, across which lie West Linn and Lake Oswego.

Oregon Route 99E runs through Oak Grove as McLoughlin Boulevard, leading north 8 miles to downtown Portland and south 4 miles to Oregon City.

Hog Island, an island in the Willamette River, lies within the boundaries of the Oak Grove census-designated place.
